Abstract: 1,127,884. Break-spinning apparatus. VYZKUMNY USTAV BAVLNARSKY. 11 Jan., 1967 [24 Feb., 1966], No. 1426/67. Heading D1D. In break-spinning, the fibres are doffed from the surface of a separating-member by an edge of the rotary spinning-chamber. In Fig. 1, the separating -member comprises a rotating roller 2 with needles on its surface which is supplied with sliver fed through a funnel 7 by a rotating roller 5.The rollers and the funnel are in a block 9, the clearance between the roller 2 and the adjacent surface 23 of the block in the region between the roller 5 and the take-off point of the fibres, which constitutes a fibre-passage 25 first decreasing and then increasing. Fixed to the top of the block is a cover 10 in which a spinning-chamber 11 is mounted for rotation. This has ventilating- apertures 12, a collecting surface 13 and a sliding surface 14, a shank 16 with a driving pulley 17 and a withdrawing tube 18 for the yarn. The open end of the chamber rotates in a groove in the block formed by a projecting part 27; at the fibre take-off point, the groove merges with the fibre-passage 25 and the edge 15 of the spinning chamber lies close to the surface of the combing-roller and acts to doff the fibres with the assistance of the reduced pressure existing inside the chamber. The radial distance of the edge 24 of the projection 27 from the rotational axis of the chamber is only slightly smaller from that of the edge 15. The air drawn out of the chamber centrifugally escapes from the cover 10 through a channel 21; in Fig. 2 not shown the cover is so constructed that the air is conducted to a point behind the edge 15 at the doffing point to assist the doffing action.

Patent GB-286289-A (GB)
Title: Improvements in manufacture of starch
IPC: C08B30/04
Filed: 1928-01-16
Abstract: 286,289. Corn Products Refining Co., (Assignees of Moffett, G. M.). March 3, 1927, [Convention date]. Starch manufacture comprises steeping the corn or other starch bearing material in dilute sulphur dioxide, solution and disintegrating it, separating the product to remove germ, bran and fibre from the starch and gluten, tabling the starch, gluten and water, filtering the starch with sulphur dioxide solution to remove solubles, returning the gluten water and the starch filtrate for re-use in the process, and comprises particularly the step of removing some of the sulphur dioxide absorbed by the corn while being steeped before the material is separated. A part of the gluten water is first used for washing steeped corn to reduce its sulphur dioxide content, and is then supplied with more sulphur dioxide and used for steeping. Sulphur dioxide is introduced only at the steep and for filtering starch. Steep tanks A1 - - A11 are shown, seven being in operation in series, connected by pipes 25 and heaters 26. The corn passes to a mill B1 after washing with water from pipe 27 connected to the gluten settlers K1, K2. This water passes through a sulphur tower C1 to the next steep. The germs, floated off in a separator D1, pass through reels E1, E2, E3 and are pressed free from water at F1. Gluten overflow water passes by pipe 28 into the reel E3, by pipe 29 to the reel E2 and thence with liquid from reel E1 to separator D1, from which the settled solid passes through a drainage reel E5 to a mill B2 and then to a separator D2 to which water passes from reels E2, E5. From separator D2 the degermed material passes through a coarse reel E6 and a fine reel E7, whence the starch liquor passes to the tables, a part being diverted, if required, by pipe 36 to the germ system. The tailings of starch, gluten and bran from reels Eti, E7 pass by pipes 37, 38 to a mill B3, and thence through coarse slop reels G1 - - G4 fed with gluten overflow water to a press F2, whence water is returned to the reel G3. Starch liquor from the reel G1 passes by pipe 44 through the reel G5 to tables. The tailings from draining reel G5 pass by pipe 45 to fine slop reels H1, H2, H3 to a press F3 to collect the bran, whence the water passes to the reel H3, these reels being watered from the starch filtrates (containing sulphur dioxide added at C2) by pipe 46. Starch liquor from the reel H1 passes to the tables. The starch, gluten water and solubles pass through cleaning shakers I1, I2 to starch table J1, whence the gluten and water pass to settlers K1. The tailings from shaker I2 pass to reel H2. A second table J2 is flushed with starch filtrate water, the starch passing through a shaker I3 to the starch filters M1, M2 and a filter press N, the filtrate passing to the shaker I3 or the fine slop system. The water may be heated at L1, L2 and L3. The filters M1, M2 are used in tandem, the starch being diluted in an intermediate vessel O. Water to which sulphur dioxide is added at C2 is supplied from hot and cold pipes 61, 62. Specification 277,572 is referred to.
Patent GB-909264-A (GB)
Title: Synthetic crystalline zeolites
IPC: F16D3/38
Filed: 1959-01-15
Abstract: A synthetic, crystalline, zeolitic molecular sieve, designated zeolite L, having a composition:- <FORM:0909264/III/1> where "M" is an exchangeable ion from Group I, II or III of the Periodic Table, the hydrogen ion or the ammonium ion, "n" is the valence of "M" and "y" is from 0 to 7, and having a specified characteristic X-ray powder diffraction pattern, is prepared in its sodium/potassium form by preparing an aqueous metal alumino-silicate mixture whose composition is as follows:-K2O(K2O+Na2O) from 0,26 to 1 (K2O+Na2O)SiO2 from 0,34 to 0,5 SiO2Al2O3 from 15 to 28 H2O(K2O+Na2O) from 15 to 51 and maintaining such a mixture at 100 DEG  to 120 DEG C. until the crystalline zeolite is formed.  The potassium/sodium form may then be ion-exchanged particularly with Ba, Ca, Ce, Li, Mg, Sr, Zn.  The zeolite crystals after formation should be washed with distilled water until the effluent pH is 9 to 12.  The ratio of the alkali metal oxide to alumina in the product is influenced by the degree of washing.  According to Examples (1) hydrated alumina was dissolved in potassium hydroxide and the potassium aluminate solution so obtained was added to an aqueous colloidal silica sol. to form a reaction mixture corresponding to 8K2O:Al2O3:2OSiO2: 2OOH2O.  The mixture was sealed in a jar and heated to 100 DEG  C. for 169 hours and the reaction mixture was washed until the effluent wash water pH was 10,5 to 11.  (2) Sodium aluminate was dissolved in sodium hydroxide and potassium hydroxide and added to an aqueous colloidal silica sol. to form a reaction mixture having a composition of 5,7K2O:5,4Na2O:Al2O3: 28SiO2:452H2O.  Crystallization and washing was carried out as in Example 1 and the zeolite product had a formula corresponding to 1,01K2O:0,09Na2O: Al2O3:6,2SiO2:5.OH2O.  Ion exchange of the so-obtained zeolites may suitably be effected with the chlorides, sulphates or nitrates of the cations concerned and the exchanging solution preferably has a pH of 5 to 12.  Reference is made to the replacement of 28% of the exchangeable cations by cerous ions by treatment of the potassium form with cerous nitrate, to 71,3% replacement by calcium ions, 73,2% re-placement by barium ions, 47,6% by lithium ions, 39,1% by magnesium ions, 48,2% by strontium ions and 22,8% replacement by zinc ions.  The zeolite may be employed as an adsorbent after activation by partial dehydration at temperatures of about 350 DEG C. under atmospheric or reduced pressure or by maintaining at room temperature under vacuum.  Reference is made to the adsorption capacity of such activated zeolites for water, carbon dioxide, oxygen, argon, benzine, thiophene, krypton, xylenes, butene, iso-butane, ammonia, sulphur dioxide, propane, propylene, nitrogen, pentane, cyclohexane, tripropylamine, tributylamine. The zeolite may be employed for separation of water from other molecules and for separating unsaturated organic compounds from mixtures with saturates and separating polar compounds from less polar compounds.

Patent GB-846660-A (GB)
Title: Switches for use in waveguides
IPC: H01P1/12
Filed: 1959-01-16
Abstract: 846,660. Waveguide switches. SPERRY RAND CORPORATION. Jan. 16, 1959 [April 3, 1958], No. 1730/59. Class 40(8). The gap between the movable parts of a mechanical waveguide switch is bridged by one or more conductors situated in the vicinity of the waveguide channels and arranged with their axes transverse to the direction of movement of the switch parts. The switch shown is of the type in which E-plane waveguide bends 40, 41 arranged within a cylindrical rotor 17 are used to connect selected pairs of terminals 13, 14, 15, 16 arranged in a stator 11. In order to prevent leakage of energy through the gap 12 between the rotor and the stator, conductive members 31, made e.g. of graphite, are arranged in slots 30 and are pressed by springs 33 against the cylindrical face of the rotor. The conductive members 31 extend axially the full length of the rotor 17 and, since the length of the rotor is greater than the broad dimension of channels 40, 41, the conductive members cannot protrude into the channels. The inner ends of the conductors are wedge-shaped and contact complementary wedge-shaped members 32 housed within the slots. The angles of the contacting wedging surfaces are slightly different and this causes the conductors 31 to be forced into contact with the sides of the slots. The conductors are arranged within a small fraction of a wavelength of the orifices of the waveguide channels. In a modification (Fig. 3, not shown), the conductive members are arranged in the rotor. Fig. 2 (not shown) illustrates the mounting of the rotor in ball-bearings arranged within a pair of end caps bolted to the stator 11. The end caps and the spindle of the rotor may be provided with air-tight seals.

Title: Process for the production of a vulcanizing accelerator for indiarubber and the product produced thereby
IPC: C08K5/00
Filed: 1925-01-20
Abstract: 251,005. North, C. O. Jan. 20, 1925. Aldehyde-aniline condensation products.-Vulcanization accelerators are made by reacting the product of condensation of equal molecules of an aliphatic aldehyde and an aromatic amine, with additional aldehyde. Aldehyde vapour, e.g. acetaldehyde, is passed into an aromatic primary amine, e.g. aniline, until the mass heats and begins to cool again, whereby a condensation, polymerization, and partial dehydration takes place. The passage of aldehyde vapour is continued for about 12 hours at a temperature of 100‹ C., and the mass is cooled for 5-6 hours to 50-60‹ C. By passing aldehyde vapour through aniline in two tanks connected in series, until the liquid in the second tank has heated and commenced to cool, a product is obtained in the first tank consisting of three molecules of aldehyde condensed with two molecules of aniline. The product is dehydrated at a temperature preferably not exceeding 105‹ C. until the moisture content does not exceed 2 per cent. This material will react with more of the same or of another aldehyde. For example, to 241 parts of this product are added 152 parts of 40 per cent formaldehyde, and the product is refluxed for about 6 hours at 100‹ C. The water is evaporated at a temperature not exceeding 115‹ C. until the moisture does not exceed 2 per cent. Other amines mentioned are o-, m-, and p-toluidines, the xylidines, and aminocymene. Specification 180,978 is referred to.

Title: Apparatus for partitioning and separating dissolved substances by fractionation between two liquid phases
IPC: B01D11/04
Filed: 1957-01-21
Abstract: An apparatus for partitioning and separating by fractionation dissolved substances between two liquid phases comprises separating vessels interconnected in a horizontal arrangement, which vessels comprise a mixing chamber provided with a stirrer, and at least one settling chamber, the mixing and settling chambers of adjacent separating vessels being connected by pipes which extend through the bottom of the vessels.  In a preferred embodiment, the mixing and settling chambers are combined in one vessel by centrally placing a cylinder in the vessel so forming an inner mixing chamber and an annular settling chamber, which are interconnected by means of ports in the cylinder.  Within the mixing chamber a ball or fork-like stirrer is mounted.  The connecting pipes between vessels are so arranged that liquids of the lighter and heavier phases are separately drawn off from the settling chambers of vessels adjacent to the vessel into which the liquids are to flow.  At the point of inflow, the two delivery pipes are concentrically arranged and protrude centrally into the mixing chamber.  Attached to the connecting pipes carrying the light phase liquid, at their lowest point, there are collector vessels from which any heavy phase liquid carried over by the light phase may be drawn off.  The apparatus may be operated continuously, and the example rotates to the separation of zirconium and hafnium in the form of their rhodamide salts, partitioned between water and ether.
